Study Notes
Thoracentesis and Pleural Fluid
- Clear, straw-colored pleural fluid post-thoracentesis indicates Congestive Heart Failure (CHF).
Spirometer Calibration
- Recorded volumes of 2.85L, 2.8L, and 2.8L suggest spirometer may have a leak.
High-Frequency Jet Ventilation
- Indicated for Bronchopleural Fistula; utilizes mean airway pressures and low tidal volumes to optimize oxygenation without worsening fistula.
Post-Anesthesia Care
- For an obtunded patient post-abdominal hysterectomy, inserting an oropharyngeal airway (OPA) is recommended due to unresponsiveness.
Ventilation Ratios
- Normal VD/VT (dead space to tidal volume) ratio for room air breathing is 20-40%.
Elevated Right Hemidiaphragm Causes
- Right-side hyperlucency with absent vascular markings suggests pneumothorax, not an elevated diaphragm.
Extubation Readiness in Pediatric Patient
- Breath sounds around the tube on auscultation indicate potential readiness for extubation in a intubated 2-year-old with croup.
Monitoring After NGT and Lasix
- Serum electrolytes must be monitored due to potential fluid loss with Lasix administration.
Vital Capacity Maneuver Instructions
- Instruct patient to inhale to Total Lung Capacity (TLC) then exhale to Residual Volume (RV) during vital capacity maneuver.
Pulmonary Edema Indicators
- Symptoms of shortness of breath, fine basilar crackles, +2 pitting edema, and a butterfly pattern on chest X-ray suggest pulmonary edema and CHF.
Total Flow with Venturi Mask
- Total flow delivered with a 28% Venturi mask at 6 L/min is calculated as 6 x 11 (flow factor = 11).
Transtracheal Oxygen Issues
- Increased work of breathing (WOB) and shortness of breath in a patient on transtracheal oxygen necessitate flushing the device with isotonic saline.
Dampened Waveform on Arterial Line
- To restore normal graphic on arterial line monitoring, check the transducer dome for air bubbles.
PEEP Study Results
- A significant rise in heart rate and drop in blood pressure at increased PEEP suggests the patient is experiencing hypovolemia.
Incentive Spirometry in Post-Op Patients
- Diminished breath sounds at lung bases and decreased inspiratory capacity post-thoracotomy may indicate complications needing further evaluation.
